Yes, a good script.
What else would like to:
1. On doubleclick close the opened file (possibly optional).
2. Uncomfortable that the fields "Name of file" and "Text in file" are different ways of filling: first - with *, second - without.
3. These fields appear as disabled (WinXP).

1. Double click opens file to editing. To close the file, you should double click on tab in edit window.
2. Wildcard characters (*?) apply only to the file names. To search for any string of characters in the file content, you must use a regular expression.
3. I don't understand this. Can you show the screenshot?

1. Quickly open the file and see that it's not that, and without moving the mouse on a tab to close it, it is convenient.
2. Different rules for filling - for the average user uncomfortable. May be necessary to look for the files using regular expressions?
3. Screenshot

What to do if the file has been previously opened. Also close it?
Probably better to select all the files and open them (Ctrl+A and Enter or click "Edit" button ), then close in AkelPad those unnecessary.

If you need to find VBS scripts, you can do it without regular expressions: "*.vbs".
If you need to find VBS and JS scripts, you have to use regular expression eg.: "(\.vbs|\.js)$".
